YARN GUIDE'.

Application lfiled July"24, 1925." Serial No. 45,747; l'

To all whomz't may concern:

lBe itknown thatI,-AnTIiUn citizen of the'Uni'ted States, resi`din'gatMilwaukee, *in the county of Milwaukee and State of Visconsin,haveinvented a `certain Guides, of `which the Vfollowingis a full,

clear,'. concise, and exact. description, reference being had to theaccompanyingA drawings, forming apart of this specification. .il

'Myinvention relates to yarn guides particularlyradaptable in circularknitting machines for guiding theyarn from the supply cones to theneedles of the needle cylinders.

These yarn guide structures comprise a'l guide bracket and a, guideplate and the object Vof the invention is to make flexible and y-eldablethe heretoforev rigid guide plates so,

as .to permit them to be set close to thelcyl# inder needles soV that'assaid needles travelV past theplates they will always be contacttherewithand will cooperatewth the plates to fully receive the yarn toyeliminate.the`

dropping of stitches to prevent tearing of the yarn, and to preventstrain onand breakage of needles heretofore caused by the catching ofthe needle hooks in knots, bunches,Y

spread sections, vor other 'irregularities in the yarn. By means. of myinvention, needle breakage is reduced to a minimunnand I also eliminatethe delay heretofore required 1in replacing the'broken needles anduntangling'. the torn fabric, whereby` the fabric. production ismaterially increased and also a uniform quality assured. 1 p

The baseof the bracket overhangs the edge" of the dial `cap and intheouter vface of the upright part 212 isV provided the vertical guidevchannel 24 for. receiving 'and guiding. the yarn guide. plate 25. At itslower end the guide plate'isexpanded laterally toform the needle guidepoint or'toe 26'and the yarn soV guide heel 27, the needle cylinder` anddial rotating yin* the direction indicatedV by the` arrow of Figure '1fThe yarn coming throughftlie guide bushing 231 extendsv through theguide opening or'eye 28 from the frontttothe rear thereof and isreceived by and .carried with the needles as the ,cylinder and dial.rotateallgin thewell known manner. y-As the cylinder and dial rotate,.f the cylinder needles travel through the camways'lS below therespective yarn guide. structures, yso thatlthe needles are raised withtheir hooked .rends .above thefguide vopening-28 as theytravel.pastiandjbehin'di the foot of. the yarn'wguide plates 25, the`needles, consecutively, as., they travel ldown-fv wardly,l hookingaround and vreceiving the yarn and carrying it dial needles. v

Theyarn fed tothe needles is not always uniform. vIt may haveknots,bunches, loose ends, spread sections, and other irregularities,and it may Waver or loop.` Unless 'the hooked ends of the cylinder`needlesv vare kept in intimate contact with the -gu'ide plates ofy theguide structures, the hooked ends may not fully. and accurately.'l :re-`

The impor-f tant object of myinvention is, therefore, to pro-vide arrangements which Awill'keep theguide plates and needles in intimate association and I accomplish thisby making the guide plates yielding and. causing them to be yieldablyheld against the needles. As shown, each guide plate, at its upper end,isv supported by a bolt 29 which passes through a plate 30 on the rearside of the vertical part 21 of the guide structure and is engaged by anut 31. A wing nut 32 extends through a slot 33` in the plate l3() landthreads into the bracket part 21.

The bolt 29 extends through the slot 34 'in the part 2l so thatthe guideplates and the back plates 30 may be shifted or ad justed vertically.rl`he bolt 29 threads into the back plate 3() and is locked by nut 31.Between ythe head of the bolt and the guide plate is inserted a leafspring 35, so that the connection between the bolt and the .plate isexible andthe plate may yield in radial direction relative to the needlecylinder. The ends of the spring are deiiected inwardly to rest againstthe plate and one end of the spring is engaged in the notch or pocket 36to lock the spring against rotation. The guide plates of the guidestructures are thus radially yieldable and are yertically adjustable. Bythis spring action the plates are held yieldingly against the hookedends of the cylinder needles 14: as these needles travel past the guideplate feet. This is shown in Figures 3 and 4. Vith this arrangement, asthe needles travel and are vertically raised toward their upwardposition ready to descend and hook the yarn, their hooks will be inclose engagement with the guide plates and complete entry of the yarn,and any irregularities therein into the hooks, will follow. Should theslugs,'knots` or other uneven .sections 'be of considerable size, theyielding guide'plates will permit them to kpass through withoutobstruction and will thus avoid breaking of the yarn and holes inthefabric.

By means of my invention the breakage of needles has been reducedas muchas seventyfive per cent, as compared to the usual breakage in machineswith the rigid This, of course, results in great saving of time andmaterial and also assures more uniform fabric.

Having described my invention, IV claim as follows: Y

l. In a circular knitting Vmachine, the combination of the needlecylinder and vertically reciprocating needles thereon, a bracketsupported abovesaid cylinder and having a yarn guide arm, a supportingplate vertically adjustable on the rear side `of said arm, a yarn guideplate reciprocable vertically along the front of said arm and secured tosaid supporting-plate to be adjustable therewith, the lower end of saidguide plate being in front ofthe reciproeating needles and having a yarnguide Vopening therethrough through which yarn may pass to be receivedby the needles, and a spring anchored at its upper end to said guideplate and pressing at its lower end against said guide plate to hold ityield-y ably toward said needles whereby the engagement between saidguide plates and needles will be yielding.

2. In a :knitting machine, the combination of a cylinder, needlesvertically reciprocable at the periphery of said cylinder, a bracketmounted above said cylinder, a supporting plate engaging against theback of said bracket, a yarn guide plate at the front of said bracket,said. bracket having a vertical slot, a connecting member extendingthrough said slot for lconnecting said guide plate with said supportingplate,

means for securing said supporting plate in vertical adjusted position,and a flat spring anchored intermediate its ends by said securing 'meansand pressing at its ends against said guide plate whereby said plate'able whereby to vertically adjust saidguid ing plate relative to saidneedles, means for securing said supporting plate in V'adjusted plate to'said supporting plate, i said supporting plate being vertically shift!position, said vguide plate having a yarn Y opening through which theyarn passes from said guiding arm to be received by the verticallyreciprocating needles, and a spring engaged under the end of said boltand pressing against said guiding plate whereby said plate may yield toabnormal pressure against it by said needles when receiving yarntherefrom.

4. In a circular knitting machine, the combination Vof a needle cylinderand needles reciprocable vertically along the periphery thereof, a yarnguide arm overhanging said l1,578,710y f4 cylinder and having a yarnguiding passageway at its upper end, a supporting plate engaging therear side of said arm,- a yarn guiding plate engagingwthe front side ofsaid arm and having a yarn guiding open# ing at its lower end throughwhich the yarn may pass'to be receivedby the needles,
